RESUMO

BACKGROUND: Previous experimental and clinical studies suggested a beneficial effect of statins, metformin, angiotensin-converting-enzyme inhibitors and angiotensin II receptor blockers (RASi) on portal hypertension. Still, their effects on hard cirrhosis-related clinical endpoints, such as variceal bleeding and bleeding-related mortality, remain to be investigated. METHODS: Thus, we recorded the use of statins, metformin and RASi in a large cohort of cirrhotic patients undergoing endoscopic band ligation (EBL) for primary (PP, n = 440) and secondary bleeding prophylaxis (SP, n = 480) between 01/2000 and 05/2020. Variceal (re-) bleeding and survival rates were compared between patients with vs. without these co-medications. RESULTS: A total of 920 cirrhotic patients with varices were included. At first EBL, median MELD was 13 and 515 (56%) patients showed ascites. Statins, metformin and RASi were used by 49 (5.3%), 74 (8%), and 91 (9.9%) patients, respectively. MELD and platelet counts were similar in patients with and without the co-medications of interest. Rates of first variceal bleeding and variceal rebleeding at 2 years were 5.2% and 11.7%, respectively. Neither of the co-medications were associated with decreased first bleeding rates (log-rank tests in PP: statins p = 0.813, metformin p = 0.862, RASi p = 0.919) nor rebleeding rates (log-rank tests in SP: statin p = 0.113, metformin p = 0.348, RASi p = 0.273). Similar mortality rates were documented in patients with and without co-medications for PP (log-rank tests: statins p = 0.630, metformin p = 0.591, RASi p = 0.064) and for SP (statins p = 0.720, metformin p = 0.584, RASi p = 0.118). CONCLUSION: In clinical practice, variceal bleeding and mortality rates of cirrhotic patients were not reduced by co-medication with statins, metformin or RASi. Nevertheless, we recommend the use of these co-medications by indication, as they may still exert beneficial effects on non-bleeding complications in patients with liver cirrhosis.

RESUMO

BACKGROUND: Prophylactic endoscopic band ligation (EBL) is used to prevent variceal bleeding in patients with liver cirrhosis. The association of thrombocytopenia, high INR (international normalized ratio) and liver dysfunction with the risk of procedure-related bleeding (PRB) remains debated and recommendations are controversial. METHODS: We analyzed real-life data of cirrhotic patients undergoing elective EBL at two large Viennese centers between Q1/2000-Q1/2018. PRB was defined as bleeding occurring within 30 days after EBL. RESULTS: We included 617 patients undergoing a total of 1178 prophylactic EBL procedures (median 2 per patient). Sixteen (2.6%) of 617 patients experienced PRB after a median of 12.5 (IQR 17.3) days with no difference in characteristics and laboratory values between the two groups. The proportion of patients with platelets (PLT) < 50 G/L or INR ≥ 1.5 was similar in patients with vs. without PRB. A higher MELD showed a non-significant association with EBL-related bleeding risk (odds ratio, OR 1.07; 95% confidence interval 95% CI 1.00-1.16, p = 0.058). While serum bilirubin was a significant predictor for PRB (OR: 1.10; 95% CI 1.03-1.18), the presence of large varices (OR 0.85 vs. small varices; 95% CI 0.20-3.84), INR (OR 0.50; 95% CI 0.10-3.14), PLT (OR 1.00; 95% CI 1.00-1.01) and the use of non-selective betablockers (OR 1.20; CI 95% 0.38-3.76) were not associated with PRB. CONCLUSION: EBL is safe and procedure-related bleedings are rare (2.6%) including in patients with thrombocytopenia < 50 G/L or high INR ≥ 1.5. Only high MELD, and especially high bilirubin seem to be linked to an increased risk of EBL-related bleeding.
